Yakaonekwa kuti mitengo yezvigadzirwa zvemakemikari mumusika zvinoramba kuderera, zvichitungamira kune kukosha kusingaenzaniswi mune zvakawanda zvinongedzo zvezvemakemikari indasitiri yemakemikari. Mitengo yakakwirira yemafuta yakawedzera iyo yekumanikidza mutengo pamakemikari indasitiri yeketeni, uye hupfumi hwekugadzira zvigadzirwa zvemakemikari zvakawanda murombo. Nekudaro, mutengo wemusika weVinyl acetate zvakare akasangana neuripo kuderera, asi purofiti yekugadzira yakaramba yakakwira uye yekugadzira hupfumi hwakanaka. Saka, neivinyl acetateMusika unochengetedza huwandu hwakanyanya hwebudiriro?

Sezvazviri pakati pekupedzisira June 2023, mutengo wemusika weVinyl acetate is 6400 yuan / ton. Zvinoenderana nemitengo yemutengo wezvekushandisa kweiyo ethylene nzira, iyo purofiti yemari yeiyo Etinty Nzira inenge 14%, nepo iyo purofiti yemari yeCalcium Carcide nzira vinyl acetate iri mune yekurasikirwa mamiriro. Pasinei nekuderera kuderera mumutengo weVinyl acetate kwegore, iyo purofiti yemubatanidzwa yakavakirwa vinyl acetate yakakwira, kusvika pakakwirira kusvika pane zvimwe zviitiko, ichiva wepamusoro purofiti chigadzirwa chemakemikari emigwagwa. Mukupesana, iyo calcium carbide nzira yeVinyl acetate yave iri mune yekurasikirwa mamiriro emakore maviri apfuura.

Nekuongorora shanduko dzemari dzinowanikwa dzevanyemba dzakavakirwa Vinyl purofiti marodhi emakore gumi neshanu muzana. Izvi zvinoratidza kuti ethylene yakavakirwa vinyl acetate yanga iri kubudirira mumakore maviri apfuura, nekubudirira kwakanaka kwakazara uye kwakasimba mibairo mibairo. Mumakore maviri apfuura, kunze kwekunge purofiti yakakosha kubva munaKurume 2022 kusvika kuChikunguru 2022, iyo calcium carbide nzira yeVinyl acetate yave iri mumatare ekurasikirwa kune dzimwe nguva nguva dzese. Kubva munaJune 2023, iyo purofiti yakadzika mwero weCalcium Carcide Nzira yeVinyl acetate yakanga yakakomberedza Carcide nzira vinyl acetate mumakore maviri apfuura yaive 0.2% kurasikirwa. Kubva pane izvi, zvinogona kuoneka kuti kubudirira kweiyo calcium carbide nzira yeVinyl acetate ndeyekushomeka, uye mamiriro ese ezvinhu ari kuratidza kurasikirwa.

Kuburikidza nekuwedzera ongororo, zvikonzero zvikuru zvekushandisa zvakakwirira zveEndylene zvakavakirwa Vinyl acetate kugadzirwa ndekwekutevera MuTherylone nzira yeVinyl acetate, iyo yunivhesiti yekudhara yeEtralene ndeye 0.35, uye iyo unit yekushandiswa kweiyo glacial acetic acid ndeye 0.72. Zvinoenderana neyevhareji mutengo muJune 2023, ethylene account yeanenge 37% yemutengo weEndylene yakavakirwa Vinyl acid account ye45%. Naizvozvo, kuti zvive nemhedzisiro yemutengo, iyo mutengo wekutenderera kweiyo glacial acetic acid ine maitiro makuru pane mutengo wekushandurwa kweVinylane Vinyl acetate, inoteverwa neEngeylene. Panyaya yekukanganisa pane mutengo weCalcium Carbide Nzira yeCalcium Carcide yeCalcium Carcide Nzira yeActic Acced Acced Acced Carcium Carcide Nzira yeCalcium Nzira Vinyl Accetate account . Naizvozvo, mune calcium carbide nzira yeVinyl acetate, iyo mutengo shanduko yecalcium carbide ine maitiro akawandisa pamutengo. Izvi zvakaringana zvakasiyana nemhedzisiro yemhedzisiro yeiyo Ethylyone nzira.

Kechipiri, kuderera muzvinhu zvekushandisa zvakabikwa uye glacial acetic acid yaive yakakosha, inotungamira kuderera kwakakosha mumitengo. Mugore rapfuura, mutengo weCFR Northeast Asia escelene yakadzikira ne33%, uye mutengo weClacial acetic acid yaderera ne33%. Nekudaro, iyo mutengo weVinyl acetate yakagadzirwa neCalcium Carbide nzira inonyanya kuomeserwa nemutengo wecalcium carbide. Mugore rapfuura, mutengo wecalcium carbide yawa necumulative 25%. Naizvozvo, kubva pamaonero ematanho maviri ekugadzira, iyo madhiri ezvinyorwa zveVinyl acetate anogadzirwa neEtraylene nzira yakadzikira zvakanyanya, uye kuderedzwa kwemutengo kwakakura kupfuura iyo yeCalcium Carbide nzira.

Kunyangwe iyo mutengo weVinyl acetate yaderera, kuderera kwayo hakuna kukosha semamwe makemikari. Zvinoenderana nekuverenga, mugore rapfuura, mutengo weVinyl acetate hwadonha ne59%, izvo zvingaite sezvakakosha, asi mamwe makemikari akasangana nedanho rakakura. Iyo yazvino isina kusimba mamiriro emusika wemakemikiti akaomesesa kuchinja. Zvinotarisirwa kuti mune ramangwana, pane mukana wakakura wekuti purofiti yemutero wemutengi, kunyanya zvigadzirwa zvakaita sePolyvinyl doro neEva, zvichachengetedzwa nekumanikidza purofiti yeVinyl acetate.

Pane kukosha kwakakomba kusingafarire mumakemikari emakemikari echireni, uye zvigadzirwa zvakawanda zviri mumamiriro emutengo wakakwira asi simbe yemutengi, zvichikonzera hupfumi hwekugadzira. Nekudaro, kunyangwe tasangana nematambudziko, iyo vinyl acetate musika wetsiva, kunyanya nekuda kwechikamu chakasiyana chemitengo yezvinhu zvakabikwa muitiro yayo yekugadzira uye kuderedzwa kwemitengo yakakonzerwa nekuderera kwemitengo yemutengo. Nekudaro, iyo isina kusimba mamiriro emangwana reChinese chemakemikari akaomesesa kuchinja. Zvinotarisirwa kuti mune ramangwana, pane mukana wakakura wekuti purofiti yemutero wemutengi, kunyanya zvigadzirwa zvakaita sePolyvinyl doro neEva, zvichachengetedzwa nekumanikidza purofiti yeVinyl acetate.
